how to make matlab functions work not starting at the first element

3 views (last 30 days)
I want to try to figure out how the findpeaks function doesn't work on the first array element, so suppose i have this code
a = [2 5 2 4 2 7 2 2 2 5 2];
pks = findpeaks(a);
but I don't want the first 5 to be read by findpeaks so it looks like it's just skipped, what code do I need to add? thank you for your attention

Hi Naufal, how about:
a = [2 5 2 4 2 7 2 2 2 5 2];
pks = findpeaks(a);
mypks = pks(2:end);
To be able to skip the first peak, you (well, MATLAB) needs to know/identify this first peak. So an easy "workaround" is to let MATLAB compute all peaks and then omit the first one by extracting all peaks starting with the second.
